Field and Laboratory Spectroscopy
Reflectance spectroscopy is the study of light as a function of wavelength that has been reflected or scattered from a solid, liquid, or gas. Spectroscopy is therefore a field and laboratory research tool that can be used to identify and map specific materials by detecting specific chemical bonds. As a result it is an excellent tool for environmental assessments, mineral mapping and exploration, vegetation communities/species and health studies, and general land management studies.
Field/Lab Spectrometers
Within the Department of Geography, Sheffield we have a laboratory facility with associated dark room, lights sources and controller PC. We have one ASD Fieldspec-3JR (0.4 - 2.5 micron) spectrometer and one ASD HH (0.1-1.1 micron) spectrometer to measure samples and provide in situ calibration of surface directional reflectance/radiance for terrestrial imaging spectroscopy studies. They also serve as laboratory spectrometers when rapid spectra are needed. We have a series ASD attachments and software to that enable us to analyse a wide range of soil, sediment, rock and vegetation samples.
